Description

Technical Field

[0001] The present invention relates to the technical field of ore grinding, in particular to rare earth ore grinding equipment. Background Art

[0002] Rare earths are known as the "gold" of industry. Due to their excellent optical, electromagnetic and other physical properties, they can be combined with other materials to form a wide variety of new materials with different properties. Their most significant function is to greatly improve the quality and performance of other products.

[0003] Chinese patent application No. 202022417692.3 discloses an ore grinding device with adjustable grinding fineness, comprising an equipment body, a feed port provided on one side of the equipment body, a workbench fixedly installed inside the equipment body, a motor provided at the top of the equipment body, and a connecting shaft connected to the output shaft of the motor, and the connecting shaft passes through the equipment body and extends into the interior of the equipment body. By providing a grinding roller and rotating the limit plate, the pull block can drive the connecting block to slide, thereby causing the telescopic rod to contract, and then causing the grinding roller to slide upward, so that the gap between its bottom end and the workbench is adjusted, so that the grinding fineness of the ore can be adjusted when the grinding roller rotates, and the fineness of the ore can be accurately adjusted.

[0004] However, this technical solution has the following problems:

[0005] When this technical solution is used to grind ore, although the grinding fineness of the ore can be adjusted by changing the distance between the workbench and the grinding roller, the ground ore particles directly enter the collection chamber from the through hole at the bottom of the workbench without being screened, resulting in the collected ore particles having different coarseness and fineness standards.

The rotating rod b31 is installed in the protective cover 35 through a connecting strip 36, and the rotating rod b31 is rotatably provided in the protective cover 35.

[0049] In this embodiment, the rare earth ore is crushed by the crushing mechanism 2, and the crushed rare earth ore is transferred to the channel 311 of the rotating rod b31 through the pipe 5. The crushed rare earth ore is ground by the grinding assembly 32, and then the ground rare earth ore is screened by the screening assembly 33. Qualified ore particles fall into the aggregate box 51, and unqualified ore particles are returned to the grinding assembly 32 for further grinding until the particles reach the qualified position. The ore particles screened by the screening assembly 33 have a uniform coarseness and fineness standard.

[0050] Preferably, Figure 3 and Figure 4As shown, the screening component 33 includes: an arc frame 331, which is installed at the other end of the rotating rod b31, and a cutout 3311 is provided at the bottom of the arc frame 331; a filter screen 332, which is installed on the cutout 3311; a round block 333, which is installed in the arc frame 331, and a V-shaped groove 3331 is provided on the top of the round block 333, and a plurality of leakage grooves 3332 are provided at the bottom of the round block 333; a central shaft 334, which passes through one end of the arc frame 331; a connecting plate 335, which is installed on the central shaft 334; and a scraper 336, which is installed on the connecting plate 335.

[0051] Further, such as Figure 3 and Figure 4 As shown, the screening assembly 33 further includes: a gear a337, which is mounted on one end of the central shaft 334; a driving portion 338, which drives the gear a337 to rotate; a stirring portion 339, which is disposed in the V-shaped groove 3331; the driving portion 338 includes: a rotating driving member b3381, which is mounted in the protective cover 35; a gear b3382, which is mounted on the output shaft of the rotating driving member b3381, and the gear a337 is meshed with the gear b3382;

[0052] like Figure 4 As shown, the stirring portion 339 includes: a rotating rod c3391, which is rotatably arranged in the V-shaped groove 3331; a square plate 3392, and multiple groups of the square plates 3392 are arranged on the rotating rod c3391, and the rotating rod c3391 is driven by a motor.

[0053] In this embodiment, the crushing mechanism 2 crushes the rare earth ore. The crushed rare earth ore is transferred through the pipe 5 to the channel 311 of the rotating rod b31. The motor drives the rotating rod b31 to rotate until the circular frame 321 faces downward. The closing assembly 34 opens the channel 311. Under the action of gravity, the crushed rare earth ore falls into the sleeve ring formed by the arc-shaped block a324 in the circular frame 321, specifically, onto the top of the spiral block a326.

[0054] Preferably, Figure 7 and Figure 8As shown, the grinding assembly 32 includes: a circular frame 321, the circular frame 321 is installed at one end of the rotating rod b31; a connecting disk 322, the connecting disk 322 is installed in the circular frame 321, and a material drop trough 3221 is provided on the connecting disk 322; a rotating rod a323, multiple groups of the rotating rods a323 are rotatably arranged on the connecting disk 322; an arc block a324, the arc block a324 is installed on the rotating rod a323, and multiple groups of the arc blocks a324 rotate to form a complete Sleeve ring; rotating shaft c325, the rotating shaft c325 is rotatably arranged in the complete sleeve ring; spiral block a326, the spiral block a326 is mounted on the rotating shaft c325, the top of the spiral block a326 is beveled; spiral block b327, the spiral block b327 is mounted on the rotating shaft c325, the top of the spiral block b327 is beveled, the thread pitch of the spiral block b327 is smaller than the thread pitch of the spiral block a326, and the rotating shaft c325 is driven by a motor.

[0055] Further, such as Figure 7 and Figure 8 As shown, the grinding assembly 32 also includes: a gear c328, which is mounted on the rotating rod a323; a gear ring c329, which is rotatably arranged at the bottom of the connecting plate 322, and the gear ring c329 is engaged with the gear c328; a rotary driving member d, which is mounted in the circular frame 321; and a gear d, which is mounted on the output shaft of the rotary driving member d, and is engaged with the gear c328 (the rotary driving member d and the gear d are not marked in the figure).

[0056] In this embodiment, since the top of the spiral block a326 is beveled, the motor drives the rotating shaft c325 to rotate, driving the spiral blocks a326 and b327 to squeeze and grind the crushed rare earth ore. The ground particles pass through the chute 3221 and fall to the bottom of the circular frame 321.

[0057] It should be noted that the thread pitch of the spiral block b327 is set to be smaller than the thread pitch of the spiral block a326, that is, the spiral block a326 performs coarse grinding on the crushed rare earth ore, and then the spiral block b327 performs fine grinding to enhance the grinding effect.

[0058] In this embodiment, the motor drives the rotating rod b31 to rotate until the arc frame 331 faces downward. Under the action of gravity, the ground particles are transferred into the arc frame 331 through the channel 311. At this time, the rotating driving member d drives the gear d to drive the gear ring c329 to rotate, driving the gear c328 to rotate, driving the arc block a324 to rotate outward to open and then rotate inward to form a reciprocating cycle, thereby driving the arc block a324 to slap the surfaces of the spiral blocks a326 and b327, so that the particles on the spiral blocks a326 and b327 fall into the arc frame 331 under the action of gravity;

[0059] Specifically, when the arc frame 331 is facing downward, the gear b3382 is meshed with the gear a337, and the connecting plate 335 is driven to rotate by the rotating driving member b3381, thereby driving the scraper 336 to scrape the particles on the filter screen 332. The filter screen 332 screens the particles, and the qualified particles pass through the filter screen 332 and fall into the collection box 51.

[0060] It should be noted that the filter 332 filters the particles, but the particles will accumulate on the filter 332, thereby affecting the screening effect. The scraper 336 is used to rotate and scrape the particles on the filter 332 (the initial state is as follows Figure 4 As shown in FIG), the scraper 336 transmits the particles accumulated on the filter screen 332 (its state is as shown in FIG). Figure 5 As shown), until the scraper 336 transfers the particles accumulated on the filter screen 332 into the V-shaped groove 3331, and after being stirred by the stirring portion 339, the particles fall onto the filter screen 332 through the leakage groove 3332, thereby enhancing the filtering effect of the filter screen 332;

[0061] Further, such as Figure 9 and Figure 10 As shown, the closing assembly 34 includes: a rotating rod b341, two groups of the rotating rods b341 are arranged in the channel 311; a closing plate 342, the closing plate 342 is installed on the rotating rod b341; a gear e343, the gear e343 is installed on the rotating rod b341, and the two groups of gears e343 are engaged with each other; a gear f344, the gear f344 is installed on one of the rotating rods b341; a gear ring f345, the gear ring f345 installed in the protective cover 35 is engaged with the gear f344, and the rotation of the gear ring f345 is driven by a motor.

[0062] In this embodiment, Figure 9As shown, the closing plate 342 closes the channel 311, and the motor drives the gear ring f345 to rotate, driving the gear f344 to rotate, thereby driving the two sets of closing plates 342 to rotate downward, thereby opening the channel 311. The motor drives the rotating rod b31 to rotate, facilitating the transfer of ore particles from the circular frame 321 to the arcuate frame 331 or from the arcuate frame 331 to the circular frame 321 under the action of gravity. Example 2:

[0063] like Figures 11-16 As shown, the components identical or corresponding to those in the first embodiment are designated by the corresponding reference numerals in the first embodiment. For simplicity, only the differences from the first embodiment are described below. The second embodiment differs from the first embodiment in that:

[0064] like Figure 11 As shown, this embodiment further includes a cleaning mechanism 4, which cleans the ore particles stuck in the filter holes of the filter 332 and straightens the deformed filter 332. Specifically, during the use of the filter 332, ore particles will get stuck in the filter holes of the filter 332, so cleaning is required.

[0065] Further, such as Figure 11 and Figure 12 As shown, the cleaning mechanism 4 includes: a rotating shaft a41; a connecting frame 42, the connecting frame 42 is installed on the rotating shaft a41; a track 43, the track 43 is installed on the connecting frame 42; a cleaning component 44, the cleaning component 44 moving on the track 43 cleans impurities on the filter 332; a regularizing component 45, the regularizing component 45 regularizes the deformed filter 332, and the rotating shaft a41 is installed on the protective cover 35 and is driven by a motor.

[0066] Preferably, Figure 13 and Figure 14 As shown, the cleaning assembly 44 includes: a rack 441, which is arranged on the track 43, and a sliding groove 431 is provided in the track 43; a rotating rod d442, which is arranged in the sliding groove 431; a gear g443, which is installed at one end of the rotating rod d442; a cleaning shaft 444, which is installed on the rotating rod d442, and a spike is provided on the surface of the cleaning shaft 444; a rotating driving member g445, which is installed at the other end of the rotating rod d442, and a limit block 4421 is provided on the rotating rod d442, and a corresponding limit groove (not marked in the figure) is provided in the track 43, and the limit block 4421 slides in the limit groove to prevent the rotating rod d442 from tilting in the sliding groove 431.

[0067] Further, such as Figure 15 and Figure 16As shown, the regular component 45 includes: a rotating shaft b451, which is arranged in the protective cover 35; an arc block b452, which is installed on the rotating shaft b451; a conical block 453, with multiple groups of conical blocks 453 slidingly arranged in the arc block b452, an airbag 454, which is arranged in the arc block b452, and the bottom of the conical block 453 is connected to the airbag 454, and the rotating shaft b451 is installed on the protective cover 35 and driven by a motor.

[0068] In this embodiment, the motor drives the rotating rod b31 to rotate until the arc frame 331 is located on the right side, and the motor drives the rotating shaft a41 to rotate 90 degrees until the track 43 fits and fits on the outside of the filter 332. The rotating driving member g445 drives the rotating rod d442 to rotate, driving the gear g443 to rotate. Due to the rotation of the gear g443 and the rack 441, the rotating rod d442 is driven to rotate and slide in the sliding groove 431, driving the cleaning shaft 444 to rotate on the outside of the filter 332. The spikes on the surface of the cleaning shaft 444 are inserted into the filter holes of the filter 332, squeezing out the particles stuck in the filter holes, thereby cleaning the filter 332.

[0069] In this embodiment, the motor drives the rotating rod b31 to rotate until the arc frame 331 is at the top, and the motor drives the rotating shaft b451 to rotate 90 degrees until the arc block b452 fits the outside of the filter 332. By introducing gas into the air bag 454, the conical block 453 is driven to insert into the filter holes of the filter 332, thereby regularizing the deformed filter holes and restoring them to their original shape, which is convenient for subsequent particle screening.

[0070] It should be noted that: Figure 17 As shown, the E state is the filter screen 332 with the filter holes deformed, and the F state is the filter screen 332 with the filter holes restored to the original shape, that is, the conical block 453 is inserted into the deformed filter holes to restore them to the original shape.

[0071] Step 1: Crushing process: Crushing mechanism 2 crushes the rare earth ore. The crushed rare earth ore is transferred to channel 311 of rotating rod b31 through pipe 5. Rotating rod b31 is driven by a motor to rotate until circular frame 321 faces downward. Closing assembly 34 opens channel 311. Under the action of gravity, the crushed rare earth ore falls into the sleeve ring formed by arc-shaped block a324 in circular frame 321.

[0072] Step 2: Grinding process: Since the top of the spiral block a326 is beveled, the motor drives the rotating shaft c325 to rotate, driving the spiral blocks a326 and b327 to squeeze and grind the crushed rare earth ore. The ground particles pass through the chute 3221 and fall to the bottom of the circular frame 321.

[0073] Step 3: Transporting process: The motor drives the rotating rod b31 to rotate until the arc frame 331 faces downward. Under the action of gravity, the ground particles are transported into the arc frame 331 through the channel 311. At this time, the rotating driving member d drives the gear d to drive the gear ring c329 to rotate, driving the gear c328 to rotate, driving the arc block a324 to rotate outward to open and then rotate inward to form a reciprocating cycle, thereby driving the arc block a324 to slap the surfaces of the spiral blocks a326 and b327, so that the particles on the spiral blocks a326 and b327 fall into the arc frame 331 under the action of gravity;

[0074] Step 4: Screening process: When the arc frame 331 is facing downward, the gear b3382 is meshed with the gear a337. The rotating driving member b3381 drives the connecting plate 335 to rotate, thereby driving the scraper 336 to scrape the particles on the filter screen 332. The filter screen 332 screens the particles, and qualified particles pass through the filter screen 332 and fall into the collection box 51.

[0075] It should be noted that the filter 332 filters the particles, but the particles will accumulate on the filter 332, thereby affecting the screening effect. The scraper 336 is used to rotate and scrape the particles on the filter 332 (the initial state is as follows Figure 4 As shown in FIG), the scraper 336 transmits the particles accumulated on the filter screen 332 (its state is as shown in FIG). Figure 5 As shown), until the scraper 336 transfers the particles accumulated on the filter screen 332 into the V-shaped groove 3331, and after being stirred by the stirring portion 339, the particles fall onto the filter screen 332 through the leakage groove 3332, thereby enhancing the filtering effect of the filter screen 332;

[0076] Step 5, cleaning process: The motor drives the rotating rod b31 to rotate until the arc frame 331 is located on the right side, and the motor drives the rotating shaft a41 to rotate 90 degrees until the track 43 fits the outside of the filter 332. The rotating driving member g445 drives the rotating rod d442 to rotate, driving the gear g443 to rotate. Due to the rotation of the gear g443 and the rack 441, the rotating rod d442 is driven to rotate and slide in the sliding groove 431, driving the cleaning shaft 444 to rotate on the outside of the filter 332. The spikes on the surface of the cleaning shaft 444 are inserted into the filter holes of the filter 332, squeezing out the particles stuck in the filter holes, thereby cleaning the filter 332.

[0077] Step 6: Regularization process: The motor drives the rotating rod b31 to rotate until the arc frame 331 is at the top, and the motor drives the rotating shaft b451 to rotate 90° until the arc block b452 fits the outside of the filter 332. By introducing gas into the airbag 454, the conical block 453 is driven to insert into the filter holes of the filter 332 to regularize the deformed filter holes and restore them to their original shape, which is convenient for subsequent particle screening.
